Ingredients List:
For the Cookies:
- 1 cup almond flour (super fine)
- ¼ cup coconut flour
- ¼ cup granulated sweetener (monk fruit or erythritol)
- ¼ cup unsalted butter, softened (or coconut oil for dairy-free)
- 1 large egg
- ½ tsp vanilla extract
- ¼ tsp salt
For the Lemon Curd Filling:
- 2 large egg yolks
- 2 tbsp unsalted butter
- 2 tbsp fresh lemon juice
- 1 tsp lemon zest
- 2 tbsp powdered sweetener (or sugar for non-keto)
Instructions:
-
Preheat Oven:
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper. -
Make the Cookie Dough:
In a mixing bowl, cream together butter and sweetener until light and fluffy. Add egg and vanilla, mixing until smooth. Stir in almond flour, coconut flour, and salt until a soft dough forms. -
Shape the Cookies:
Scoop tablespoon-sized balls of dough and roll them smooth. Place on the baking sheet and gently press the center with your thumb to create a small well. -
Bake (Round 1):
Bake for 8–9 minutes until the edges are just starting to set. -
Prepare the Lemon Curd:
In a small saucepan over low heat, whisk together egg yolks, sweetener, lemon juice, and zest. Add butter, stirring constantly for 3–4 minutes until thickened. Remove from heat and let cool. -
Fill & Bake (Round 2):
Remove cookies from the oven, re-press the center wells if needed, and spoon in lemon curd. Return to the oven and bake an additional 3–5 minutes. -
Cool & Serve:
Let cookies cool on the pan for 5 minutes, then transfer to a rack to cool completely. The lemon curd will firm up as it cools.
Additional Notes:
- For a glossy look, brush warm lemon curd with a tiny bit of melted butter.
- Dust with powdered sweetener for presentation.
